Ghidra is a powerful open-source reverse engineering framework developed by the National Security Agency (NSA). It is designed to analyze compiled binaries when source code is unavailable. Security researchers, malware analysts, firmware engineers, and cybersecurity students widely use Ghidra for static analysis, vulnerability discovery, and binary inspection.
Released publicly in 2019, Ghidra quickly became one of the most trusted reverse engineering tools because it offers enterprise-level capabilities completely free of cost.
What Is Ghidra?
Ghidra is a Software Reverse Engineering (SRE) framework that converts low-level machine instructions into readable assembly and high-level C-like pseudocode. It allows analysts to understand program behavior without needing access to the original source code.
